Hi,
it is probably not a good idea in general to connect to the database
during the extension installation. I don't know the reasons for doing it
during the installation but i would think about it. Keep the
registration short and easy.
Anyway that wouldn't solve your problem and would only postpone it on
later during the runtime of the office.
I am not sure if it really helps in this case but often it is a problem
with the context classloader.
Before you call in any external library it is good practice (and i
highly recommend it) to set the context class loader accordingly. Many
external libs rely on a well prepared default class loader (including
the whole classpath etc.). In case of UNO components we prepare "private
class loaders" for every extension and you have to ensure that
everything you need is configured in the manifest.
Try the following before you call in the external lib
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
...
// external code
...
Thread.currentThread().setContextClassLoader(cl);
